Tip of the Week: For the Love of Organic Strawberries – Part 1

Whether you choose early-, mid- or late-season June-bearers, the smaller but more frequent everbearers, or the young upstart day-neutrals, a freshly picked, perfectly ripened homegrown strawberry does not exist in the same galaxy as its cardboard cutout, dry-as-sawdust store-bought brethren, let alone on the same planet.

Here are some tips on how you can grow the biggest, most juicy and flavorful strawberries ever—without using harmful pesticides or other chemicals!

**********************
When I read a few years ago that conventionally grown strawberries retained more toxic pesticide residues than just about any other fruit, I knew I had to start growing my own—because I loooooove strawberries. With the cost of organic strawberries—in season—hovering around $3/pint (I can’t even imagine what they cost now), I was eating a lot of pesticide-residue-riddled berries.

Not anymore.

The 3S’s: Sun, Soil and Regular Sousing
Although strawberries are easy to grow, these highly versatile nectars of the gardening gods require an abundance of the basic elements of photosynthetic life: lots of sun (at least 6 hours of direct sun a day), slightly acidic soil (between 5.5 and 6.5 pH, according to eHow.com) that is rich in organic matter and allows for good drainage, and about an inch of water per week—especially when the fruit is developing.

I’ve also read that, when choosing where to put the patch, to be careful to avoid planting strawberries where tomatoes, potatoes, peppers, eggplants or raspberries have been grown for the past several years. These plants can harbor verticillium wilt, which is particularly hazardous to strawberries. Every university extension site I visited, with the exception of Ohio State’s, listed chemical solutions for treating this pervasive fungus. Based on what I’ve read, the best organic solution is prevention.

Good drainage is important because strawberries have shallow root systems. They need plenty of water for big, juicy berries but cannot abide sitting in standing water and will rot. Some experts recommend planting strawberries in hills or in raised beds loaded with lots of well-composted organic materials.

How I did it. Other than the advice not to plant strawberries where tomatoes had been, I didn’t really know any of this stuff when I first planted my strawberries. I picked a section of a dormant flower bed for my primary patch. The fall before planting I pulled up all the weeds and turned the soil, which had been sitting fallow for at least a year before I secured my patch at the community garden. The nun who had tended the garden of which my patch was only about a third was very ill and couldn’t keep up with her garden. She died the winter before I began leaving voicemails for Sister Rita, pestering her for a veggie patch of my own.

My first fall at the patch I dumped a couple of 40 lb bags of organic mushroom compost on the patch (my own newly established compost pile wasn’t “ripe” yet) and worked it lightly into the soil. And that was pretty much it.

Everbearing, June-bearing—or Day-neutral?
When it came time to actually pick out what type of strawberries I wanted to grow, I was faced with an overwhelming array of choices. Because I had spent a couple of summers and many, many weekends working for my dad on his organic farm in southwestern Michigan, I knew there were everbearing strawberries, which, under the right conditions, would produce throughout the growing season, and June-bearing strawberries, which, like the name implies, bear fruit just once per year in late spring to early summer.

What I didn’t know was that within each broad category were a number of different choices: For instance, June-bearers have early-, mid- and late-season varieties. I suppose an ambitious gardener—or a strawberry addict—could cultivate all three to keep fresh strawberries on the table for a couple of months rather than the typical 3-week production cycle.

Everbearers produce smaller berries a couple of times a year (spring and fall) and don’t shoot off as many runners (picture spider plant offshoots that, instead of dangling from a hanging basket, spread along the ground, and then start establishing new roots once far enough away from the mother plant) as June-bearers.

Then there’s a newer cultivar I knew nothing about called the day-neutral. According to the Purdue University Extension office’s Yard and Garden News Web page, day-neutrals are a true everbearer and can produce fruit throughout the growing season, as long as it doesn’t get too hot.

How I did it. Although the space allotted for my strawberry patch was pretty small (about 4’ x 4’) I decided to go with the June-bearers. Aesthetics are important to me; I wanted to grow big, juicy, luscious strawberries, not the puny (to me) everbearers my dad grew on his farm. I figured, so what if I could enjoy them fresh for only a few weeks? I could (and did) enjoy the frozen berries I put up for months!

By the third season I was very pleased with my choice. My strawberries, picked ripe, not green and spiny like the flavorless store-bought berries, rivaled what you could buy at Jewel or Safeway in size and had irresistibly incomparable flavor. My mouth is watering just thinking about them. I can’t wait for spring!

On the other hand, although day-neutrals can produce throughout the growing season, they practically have to be treated as annuals, which means you have to replant them every year.

Next week I will finish my ode to strawberries with tips on their planting and care that will assure you of the most delicious strawberries you have ever tasted.

12-Step Program for Worm Smokers?

I’m concerned one of my gardening buddies has a problem. Amanda Thomsen, newest blogger for Horticulture magazine (you can follow her on Twitter at @kissmyaster), posted the following: “I covered up the vermiculture smell with incense-now I smell like I’ve been smoking worms and I’m trying to hide it.”

Apparently, Amanda separated out some worms from her worm bin to give to a friend who was starting his or her own vermicompost. Amanda’s husband commented that she smelled “worm-y,” so Amanda lit some incense.

Concerned for my friend’s well-being, I responded promptly: “You do know that smoking worms leads to harder stuff; next thing you know, you’ll be popping rolly pollies (aka pill bugs).”

If anybody knows of a 12-step program for gardening junkies, please send me (@FarmerPhoebe) or @kissmyaster the link right away. Lives hang in the balance.
